Conciseness

The body is purposeful and example-driven, but sizable portions of the Language section (active vs passive voice, plain language, one-idea-per-sentence, the 'Words to Watch' and 'Avoid' lists) restate general writing principles Claude already knows; while recontextualized as wiki house style, they could be tightened, matching the 'mostly efficient with some unnecessary explanation' anchor.

Actionability

Guidance is concrete and actionable for an instruction-only skill: specific commands (wiki_list, wiki_search, wiki_read), the link format [display text](wiki:slug), numeric rules (3-5 related slugs, 15-25 word average), and good/bad examples covering tone, leads, links, and edit summaries; a few areas stay principle-based rather than step-based, holding it at 4.

Workflow Clarity

Clear sequences exist for 'Before Writing' (search, decide expand vs create) and 'Editing Existing Pages' (read full page, match style, verify corrections, preserve info) with real checkpoints (read-before-edit, verify-before-apply, six-month accuracy test); the only gap is the absence of an explicit post-edit verification/re-read loop, so it stays at 4.

Progressive Disclosure

The single file is well-organized with logical ## and ### headings, no nested references, and easy navigation; with no bundle files present, content is appropriately kept inline in one cohesive standards document, but the page-type definitions or words-to-watch lists could in principle be split out, leaving minor organization gaps at 4.

Specificity

Names the domain ('wiki pages') and two actions ('creating or substantially editing') but the colon-list ('language, tone, structure, page types, linking discipline, what separates useful articles from filler') enumerates topical aspects rather than several concrete executable actions, so it is not comprehensive enough for a 4.

Completeness

Both 'what' (the colon-list of editorial concerns) and 'when' ('Use when creating or substantially editing wiki pages') are present and explicit; the 'what' is conveyed as a list of aspects rather than a crisp action statement, so it does not reach the fully concrete 5 anchor.

Trigger Term Quality

The natural phrase 'creating or substantially editing wiki pages' is exactly what a user would say, with good coverage of 'wiki pages' and the create/edit verbs; a few synonyms (wiki article, knowledge base, documentation) are missing, keeping it just below 5.

Distinctiveness Conflict Risk

'Wiki pages' is a clear, fairly distinct niche with an explicit trigger, but the craft/process framing carries minor overlap risk with general writing or documentation skills, placing it just below the minimal-conflict 5 anchor.
